Rihanna's longer-on-top style is rolled up and back for a glam evening look. Get the look:

1. Apply medium-hold gel to damp hair and comb through to distribute. 2. Blow dry the top with a 1-inch round brush. Roll hair up and away from the face to create the smooth, glam curls. Once hair is dry, pin back any strands that aren't cooperating.3. Set with firm-hold hairspray.
